Claim Pool Rewards

Learn how to claim rewards accrued through Morpho, onchain via a smart contract & offchain via ethers.js.

Claim rewards accrued from the underlying pool through Morpho, offchain through Etherscan or with ethers.js, or onchain using a smart contract. Here are concrete examples 👇
